We have been investigating two problems reported after launch of v3.4.0 on Calamari, located the issues and will be releasing a runtime upgrade to address them, with the vote starting Sunday Oct. 10. Due to the urgent nature of this upgrade, we will fast-track the vote to conclude after 24 hours, with a tentative live-on-calamari date of Monday Oct. 11. This release pushed an increase to XCM weights on Calamari, causing XCM transfers from Moonriver dApps to Calamari to start failing due to lack of funds to execute the Calamari-side transfer of the XCM. We are working together with Moonbeam to reenable XCM between our chains ASAP and decide whether to recover the funds frozen in the XCM transaction on the Moonriver or on the Calamari side. The following is a list of all stuck XCM transactions issued before XCM was halted with a total economic value of 5000 USD. If you issued an XCM transfer from Moonbeam to Calamari on Oct 6 or later and it failed, but you don’t see your transaction on the list, please contact us! 2. Staking Rewards The code shipped with the v3.4.0 upgrade to staking unintentionally circumvents the round-robin block-producer assignment, leading to collators competing for inclusion of their block on each slot instead of taking turns. Collators running fast and well-connected machines thus produce a larger proportion of blocks each round than they should, claim more of the rewards and leave fewer for the rest. The total amount of KMA created for rewards every 6 hours is normal but the distribution is currently skewed towards more powerful collators. A fix has been identified and will be deployed to Calamari in the next days. You’ll be seeing higher or lower reward payouts than the estimated APY showing in the delegation app depending on the collator hardware your stake is backing until then.
